3 Claimsl I;

This invention relates to. devicesfor use in; constructing molds. forplastic walls. to. be, built in situ.

An object of? the invention is the provision of, a wall moldconstruction in which vertical bars are secured removablyto boltsembedded. in the foundation of a building; said bolts also main tamingin place for-m board retainers, that are provided with ribs forreceiving: andv spacingthe form boards: between which the plastic matrials are poured or tamped, said form boards being readily removable;after the materials have se Another object of the invention. s theprovision of" a wall mold construc ion, in. hich; a plurality ofvertical bars and transverse. bars. which have spacing ribs arecoordinated o a foundation ofa. building for removably holding] aplurality of form boards: to provide spaces for receiving: plasticmaterials. to form eith r a single wall or spaced. double walls, thetransverse; bars bein embedded in the finished walls; while the verticalbars and form boards. being removable for use in constructing proressive elevated courses of the wall, means being embedded in thefoundation for removably retaining the Vertical bars inoperativepositions- A fur h r object of. he invention is the .p ovisionof a wall. old construction in which trans verse bars are bolted to. apreviously formed foundation with vertical bars having lateral flangesat the opposite ends thereof, one of the. flang of ch ertical. bar b inheld. in place by one of the bolts. so that ribs on the. tran verse barswill, cooperate with the vertical bars for retaining form boards inposition to provide spaces into. which plastic materials are poured. ortanned, the other flanges on. the vertical bars furnishing supports .foradditional vertical. bars and transverse. bars to retain elevated formboards in place for applying a succeeding course of plastic materialsto. the preceding course, the transverse bars remaining embedded in the.bias: tic materials. to tie parallel spaced walls together, the formboards and vertical bars being. removable.

The invention consists in, the. novel construction, arrangement and.combinations of parts hereinafter morev particularly described andclaimed.

In. the drawings Flame 1. is. a. view in perspective f he top at afoundation showing bolts embedded therein for receiving the perforatedends of ribbed transverse bars.

Figure 5, is a view in perspective of a section of a foundation with setspaced walls risin therefrom showing the last stage in the formation of;a first course and disclosing the inner form boards in the process ofremoval, and

Figure. 6 is a view in perspective of the completed first course shownin Figure 5 and disclosing additional transverse bars and vertical barssecured to top flanges of the vertical bars employed in the: firstcourse for holding elevated form boards to provide a mold for asucceeding course; of plastic materials.

Referring more particularly to Figure 1, l0 designates the usualfoundation of plastic mas. terials which are set in a channel. or trenchdug in. the ground. Pairs of bolts H are placed in the foundation beforethe plastic materials have set. The distance between each pair of boltstransversely of the foundation is determined by passages inv the. endsof transverse bars l2, while the, distance between the pairs of boltslengthwise of the foundation is determined by the length of form boardsl3 and I4,

Each transverse, bar l2 has an upstanding short rib 55 adjacent each endof sad bar, a centrally disposed rib l6 and a pair of ribs ll atv eachside cf the rib id. The number and spacing of the ribs will depend uponthe number and the positions of form, boards required for building aparticular type or wall.

A vertical bar or form board support 20 has a lateral flange 2| at thelower end and said flange is provided with a perforation to receive oneof the bolts 5! A nut 2.2 secures said flange to an end. of a.transverse, bar 12. so that the bars 20 will he held, in. verticalpositions. The perforations in the flanges 2i are so placed that. theinner faces of the bars 20 will be spaced a sufficient distance from theouter ribs I5 that the. lower 3 edges of the form boards I3 will bereceived neatly between the ribs I5 and the bars 20. The upper end ofeach vertical bar has a lateral flange 23 provided with a perforation 24for a purpose which will be presentedly explained.

The inner form boards I4 have the lower edges received between thecentral rib I6 and an adjacent rib I'I so that the inner boards I4 willprovide an air space between the set vertical walls 25 and 26 (Figures 5and 6) After the form boards are placed in position as shown in Figure 3upper transverse bars 30 are placed on the tops of said boards withperforations in the ends of said bars aligning with the perforations 24in the upper flanges 23 at the tops of the vertical bars 20. The bars 30are then secured to the flanges 23 by bolts 3| and nuts 32 (Figure 4) Arib 33 is located on the upper surface of the bar 30 adjacent each endthereof and pairs of ribs 34 and 35 are disposed between the end ribs33. The lower edge of an outer form board (not shown) is adapted to bereceived between an outer' rib 33 and an elevated vertical bar 36secured by the bolts 3| to the ends of the transverse bars 30 (Figure6). The pairs of ribs 34 and 35 are adapted to receive the lower edgesof a pair of inner form boards (not shown).

The under face of each transverse bar, adjacent each end, has adepending rib 43 which bears against the inner upper faces of the formboards I3. The under face of each transverse bar 33 has also pairs ofdepending ribs 4| which receive the upper edges of the inner form boardsI i (Figure 4).

The form boards I3 and M are cut the proper size from plywood composedof three layers. These form boards are treated with an oil to renderthem impervious to moisture so that they will not contract or expand inuse or in storage after having been subjected to the wet plastics.

In erecting walls with the molds of knock-down construction, thefoundation I0 is laid first and the pairs of bolts II are forced intothe wet plastic. The transverse bars I2 are applied with theperforations in the ends of said bars receiving said bolts. The verticalform supporting bars are positioned as shown in Figure 2 and the nuts 22are screwed up tight on the flanges 2| after the cement has set.

The inner form boards I4 are placed upon the transverse bars I2 with thelower edges seated on the transverse bars on opposite sides of thecentrally disposed rib I6. The outer form boards I3 are next positionedwith the lower edges seated between the end ribs I5 and the verticalbars 20, the outer faces of the form boards being in contact with theinner faces of said vertical bars as shown in Figure 3.

Figure 4 discloses the application of the top transverse bars 30 to theupper flanges 23 of the vertical bars 20 where bolts 3! and nuts 32secure the transverse bars to said flanges. When the transverse bars 33are laid upon the flanges 23, the pairs of dependin ribs 4| are fittedover the upper edges of the form boards I4 while the end ribs engage theinner faces of the upper ends of the form boards I 3 forcing the boardsin contact with the vertical bars 20.

The plastic materials are ready to be poured into the spaces between thepairs of form boards l3 and I4. When the materials have set, the uppertransverse bars 30 are removed after which the inner form boards I3 arewithdrawn (Figure5).

The next course can only be applied after the transverse bars arereturned and the succeeding uprights or form supporting bars 36 aresecured in place by the bolts 3| and nuts 32. The removed form boards I4are then seated in the pins of upstanding ribs 34 and 35 while a pair ofadditional outer form boards are so placed that the lower edges thereofwill be seated between the upstanding end ribs 33 and the adjacentlydisposed vertical bars 35. A third group of transverse bars are securedto the upper end of the vertical bars 36 with corresponding dependingribs to engage and hold the upper ends of the form boards in place.

Since all of the additional transverse bars and vertical bars requiredto raise the walls to the proper height are identical with thetransverse bars 30 and the vertical bars 20 no further disclosure needbe set forth. However, when the extreme height of the wall has beenreached transverse bars which are identical with those shown at I2 inFigure 1 and Figure 2 are employed although said bars are reversed sothat the fins or ribs will be in pending positions while the uppersurfaces will be flat.

When the walls have been completed the vertical bars 20 and 36 togetherwith any succeeding bars will be removed as will be all the outer moldboards I3 which have been returned in place during the progressivebuilding stages of the walls.

When pairs of spaced walls 25 and 23 are formed as shown in Figures 5and 6, all the transverse bars will remain embedded in the set plasticmaterials and will act as the rods between said walls. 011 the otherhand, when single walls are constructed the inner form boards will beeliminated as will be the upstanding and depending ribs which arerequired for positioning said inner form boards.

The projecting ends of the transverse bars may be readily broken offsince the transverse bars are made of cast iron.
